Napoli put three unanswered goals past Empoli in a dominant display at the Maradona to move within three points of the Serie A summit.
Scott McTominay opened the scoring when he latched onto Romelu Lukaku's pass and carried the ball forward before firing in a low drive from 20 yards out.
Ten minutes into the second half, Lukaku made it 2-0 with a tidy control and finish from inside the area.
The Belgian then provided the cross for McTominay to meet with a towering header and notch his second of the game.
